The Elements of Weather

Understanding Basic Concepts
- explain the difference between weather and climate and the factors that influence both of these systems
- identify patterns in air movement
- identify the effects of air pressure


What is Weather?

http://oncampus.richmond.edu/academics/education/projects/webunits/weather/how.html

1. Define weather:weather is low pressure meaning lousy weather(cold) or its high pressure meaning happy highs(nice day).
2. What four factors affect weather:The air,the sun ,water,the earths movement are the four factors of weather.


Weather vs Climate

3. What is the difference between climate and weather? Climate is along period in time. The weather is just day to day weather!!

Air Pressure

4. Complete the following chart:

High Pressure

Low Pressure

Air movement (up or down)
up.
.down
Temperature of air
high.
warm weather
.
cold​ weather
Wind movement at ground
.air flowing in counter clockwise
flowing out clockwise at the ground.
Expected weather
air slowly descends
. it rises and sinks often forming
clouds and precipitation

Measuring the Weather

Developing Skills of Inquiry, Design and Communication
- design, construct, and test a variety of weather instruments
- use appropriate vocabulary, including correct science and technology terminology, in describing their investigations and observations


The following web site describes some of the instruments meteorologists use to collect data about the weather.

Use the information to complete the chart.
The source of this information is American so you may have to determine the equivalent metric unit to record in the chart.


Instrument Name
What It Measures
Unit of Measurement
.Barometer
measures air pressure
measures atmospheric pressure in Millibars
Anometer.
measures wind speed
.
measures wind speed in mph
rain guage
measures the amount of rain fall

measures in nm
thermometer.
measure air temperature
measures 32 to 213
campell stokes recorder

measures in north,south,eastand west
meterorologist
it measures the amount of cloud cover
measures from 1 to 8.0 oktas
hygrometer measures the amount of humidity measures in F and C

Clouds

Understanding Basic Concepts
- explain the formation of clouds and the effects of different cloud formations on weather and climate


Use this web site to answer the following questions.
http://oncampus.richmond.edu/academics/education/projects/webunits/weather/clouds.html

1. What are clouds?clouds are a major part in weather,clouds make snow,rain.sleet.hail....fall from the sky
2. Explain how clouds form.clouds form when air cools below its saturation point and causes water vaper to condense into tiny water droplets.
3. What are the 3 "families" of clouds and what do their Latin names mean?cirrus means,curl of hair and cumulus means,heap and stratus means,layer.
4. Follow the links to learn about each type of cloud and then complete the table on the next page.
To help you identify clouds, download, print and construct the following "Cloud Key".

Forecasting

Understanding Basic Concepts
-recognize large-scale and local weather systems
- predict local weather patterns using data from their own observations of weather and from weather reports
- identify patterns in air movement


Read the details at http://weathereye.kgan.com/cadet/forecast/camp.html and follow the links.
The following questions and organizers will help you keep track of the crucial information you’ll need.

Cloud Forecasting

Cloud Type
Description
Possible Weather
cirrus
High level, wispy, hair-like, white tufts, or filaments. Higher than mountains.
no storm
altocumulus
Middle level layered cloud, rippled elements, generally white, sky showing through
no storm
nimbostratus
Thicker and darker than stratus, dark grey along base, foggy
possible a storm could happen
cumulus
Low level, individual cells, puffy, like lumps of cotton, flat bases.
no storm
cumulonimbus
Low level, very large cauliflower-shaped or anvil-shaped tops. Thunderstorms, lightning, rain and tornadoes.

Warm and Cold Fronts

Understanding Basic Concepts
- explain the difference between warm and cold fronts and the factors that influence both of these systems
- identify types of weather associated with each front

http://www.classzone.com/books/earth_science/terc/content/visualizations/es2002/es2002page01.cfm?chapter_no=visualization


Write the capital letter A or B at the end each sentence.

A = Cold Front B = Warm Front

1. Cool air mass - warm air mass moves in.
2. Warm air mass - cool air mass moves in.

3. Brings gentle rains that may last for hours or days.B
4. Strong winds are formed followed by heavy rain, crashing
thunder, and flashing lightning.A
5. When the front passes, the temperature warms up and it
becomes humid.B
6. When the front passes, the weather turns cooler.A
7. Farmer Brown prefers this type of front.B
8. Usually happens and is over with quicklyA
